initialize a mobile IP registration procedure, the mobile IP registration procedure being performed by a mobile node (MN).
16. The AR according to claim 15 wherein the at least one predefined criterion is selected from a group comprising:
determining whether a time for which the tunnel has been inactivity exceeds a predetermined value;
determining whether data traffic between the two ARs is real time data traffic;
determining whether CPU utilization at the AR exceeds a configurable CPU utilization threshold value;
determining whether a time for which the MN has been registered with one of the two ARs exceeds a tunnel lifetime of the MN; and
determining whether buffer utilization at the AR exceeds a buffer utilization threshold value.
